We have a community at LJ for a Homestuck Spanish translation!
We're advancing slowly but with all our heart poured on it. It sure is a big project! One we hope we make work in the best possible way.
If you like Homestuck and speak spanish, we'd love to hear your thoughts
Also coming soon: http://homestuck-esp.livejournal.com/
It's not ready yet - I need to write down some rules and make a nice layout for it, but it's made already! And we need members. Fanfics, fanart, icons and general discussion should go there.
